The specific embodiment
Below, with reference to accompanying drawing, the trac. that has strengthened pooling feature of the present invention is specifically described.
As shown in Figure 1, the present invention is as one embodiment, operator's compartment (10) with operator's saddle is positioned at the upper left-hand of car body (30), with rotatable S. A. (41), is connected and crank arm (40) that can rotate are configured in the space that described operator's compartment (10) is not set and realize balance.; have following structure: described operator's compartment (10) is positioned between the front-wheel (21) and trailing wheel (22) of trac.; and on the left of being configured in simultaneously; thereby the side at described operator's compartment (10) forms certain space; in the situation that do not use described cranking arm (40) to carry out operation, described cranking arm (40) is configured in described certain space.The invention is not restricted to the structure shown in Fig. 1.
Power transmission structure to applicable trac. of the present invention is briefly described as follows: the rotary power produced from driving engine sections (not shown) such as diesel motors is passed to change-speed box (71), from described change-speed box (71) to PTO axle (77), with central differential gear (72) transferring power that the driving rotating speed of described front-wheel (21) and trailing wheel (22) is regulated, described central differential gear (72) is to trailing wheel cardan shaft (74) transferring power of the front-wheel cardan shaft (73) that drives front-wheel (21) and driving trailing wheel.
In addition, in the present invention, the front axle (50) of the described front-wheel of driving (21) that is arranged at the place ahead of trac. is positioned at top with respect to the back axle (60) that drives described trailing wheel, makes at described front-wheel (21) and has carried out maximum while turning to, and described front axle (50) is interference-free.
With reference to Fig. 2 to Fig. 6, the buffer structure of described front axle (50) is described as follows.
Left and right arranges a pair of upper links (51) and lower link (52), one end of this upper links (51) and lower link (52) respectively with the chain connection up and down of described front axle (50), and this upper links (51) and lower link (52) are extended along the length direction of described car body, the other end of described upper links (51) and lower link (52) is connected with the left and right sides of described car body respectively and forms four joint bar linkage structures, thereby is subject to even have described front axle (50) structure that outside impact also can wander up and down.
In addition, described front axle (50) with chain connection the close part of part of described upper links (51) and lower link (52) assistant cylinder (53) is set respectively, thereby moving about and relaxing the impact of described front axle (50) sharply do not occur when described front axle (50) wander up and down.Described assistant cylinder (53) preferably is arranged to the above height of the height identical with described front axle (50) or its, makes at described front-wheel (21) and has carried out maximum while turning to, and is not subject to the interference of described front-wheel (21).
Described assistant cylinder (53) is connected with the pressure accumulator that is filled with pressure gas (54), and at described assistant cylinder (53) while moving up and down, expansion and sorption by described nitrogen play the effect that described front axle (50) is cushioned up and down.
Described gas is preferably nitrogen, its reason be because nitrogen be in compressibi1ity gas, the most easily obtain, low price, reactive little, there is imcombustibility, nontoxicity and without the gas of the safety of combustion-supporting property.
In addition, in order further to relax the impact of described front axle (50), also can possess and described assistant cylinder (53) bumper (55) side by side.Described bumper (55) section has within it been filled the weighting material of gas, wet goods, can increase the wander up and down attenuation power of described assistant cylinder (53).
In addition, trac. has mobile situation and static and situation that carry out operation, carry out operation in the situation that described trac. is static, described front axle (50) not wander up and down for well, therefore stop the work of described pressure accumulator (54), make the buffer structure of described front axle (50) not work, thereby can cut off pressure gas or the hydraulic pressure of supplying with to described assistant cylinder (53).
In addition, in order to prevent described front axle (50) sway, also can further possess sway and prevent connecting rod (57), this sway prevents an end and described car body (30) chain connection, the other end and described front axle (50) chain connection of connecting rod (57).Because sway prevents connecting rod (57), described front axle (50) can be prevented from sway, but can wander up and down.
In addition, described front axle (50) form "
" word shape, at described front-wheel (21), to the left or during right hand steering, make described front-wheel (21) enter into the below of described four joint bar linkage structures.
In addition, for the impact to described front axle (50) realizes better buffering, also yielding rubber (56) can be set on the top of described front axle (50).
Below, with reference to Fig. 2 to Fig. 6, the buffer structure of described back axle (60) is described.
The buffer structure of described back axle (60) is configured to as follows: the outstanding arm (61) that a pair of prolongation of the length direction along trac. is set in described back axle (60) left and right, by the other end of described arm (61) and described car body (30) chain connection, thereby described a pair of arm (61) and described back axle (60) are set to, with respect to left and right directions, in irremovable mode, fix, and, with respect to above-below direction, can move about.In such structure, the overturning danger in the time of can avoiding travelling rotation.
In addition, in the close part with being provided with described arm (61) part of described back axle (60), assistant cylinder (62) is set respectively, when described back axle (60) wander up and down, prevents moving about sharply, thereby relax the impact of described back axle (60).Described assistant cylinder (62) is connected with the pressure accumulator that is filled with pressure gas (63), and at described assistant cylinder (62) while moving up and down, expansion and sorption by described nitrogen play the effect moved up and down sharply that prevents described back axle (60).
In addition, in order further to relax the impact of described back axle (60), also can possess and described assistant cylinder (62) bumper (64) side by side.Described bumper (64) section within it is filled with gas, wet goods weighting material, can increase the wander up and down attenuation power of described assistant cylinder (62).
In addition, carry out operation in the situation that described trac. is static, described back axle (60) not wander up and down for well, therefore stop the work of described pressure accumulator (63), make the buffer structure of described back axle (60) not work, thereby can cut off pressure gas or the hydraulic pressure of supplying with to described assistant cylinder (62).
In addition, in order to carry out the better buffering to the impact of described back axle (60), on the top of described back axle (60), yielding rubber (65) can further be set.
The present invention can possess the buffer structure of described front axle described above (50) and the buffer structure of described back axle (60) simultaneously.
Above, with reference to the preferred embodiments of the present invention, be illustrated, but those skilled in the art should be understood that in the scope that does not break away from thought of the present invention that claims put down in writing and field and can carry out various modifications and changes to the present invention.
